Ni-CI Nickel-base Electrode

Download Catalog
Ni-CI welding electrodes are specialized consumables used for welding cast iron. They are composed of a nickel-based core wire and a specialized coating that minimizes cracking and ensures a smooth, machinable weld. These electrodes are ideal for welding cast iron due to their ability to: Reduce cracking: The nickel-based compo...

  • Key Features:

    • Core: Primarily composed of nickel.2
    • Coating: Specially formulated to minimize cracking and ensure a smooth, machinable weld.3

  • Applications:

    • Welding cast iron to itself: Repairing cracks, filling voids, and building up worn areas in cast iron components.4
    • Joining cast iron to other metals: Such as steel.5

  • Benefits:

    • Low cracking tendency: Helps prevent the formation of cracks in the weld and surrounding base metal, a common issue with cast iron welding.6
    • Good machinability: The weld metal is easily machined, allowing for accurate finishing and shaping.7
    • Versatility: Suitable for various cast iron grades, including gray, ductile, and malleable iron.8
